Application filed Novernber 2, 1926. Serial No. 145,842.

This invention relates to stapling machines and particularly to machines for forc ing relatively wide staples through boxes used for containing or transporting chicks. The general object of'theinvention'is to providea machine of this character which is very simple, may beeasily mounted, and which has been found to be thoroughly effec'tive in practice and whereby a staple may be forced through thepasteboard'of theybox and the outer ends of the staple overturned upon the flap of the box. j

My invention is illustrated in the accompanying drawings wherein V Figure l-isa side-elevation of a stapling m'achineconstru'cted in accordance with my invention i Fig. 2 is a View; i is. a the plunger; p

"Referring to these drawings the support for thestapl-ing machinecon'sists of a'pl'ank or equivalent member designated 10, which is preferably ofha-rd WO OZCl 'andwhich may be fastened against the wall of a "house, a

fragmentary vertical sectional face View of the upperend of post, ,or s any other structure, Attached to f -of the metal plate 11 is an outwardly and '1 downwardly extending bracket 17. The

the face of this plank 10 is a plate 11 of metal which is attached by means of bolts .or screws12and which has a slot 13 formed in its face. Extending from theplate 11 is a vertically movable arm l t, the inner end of whichfis curved, las at'15,,for insertion within the s'lot'13', the plank 10 being re commodate this curved portion. A: cotter pin or like stop 16 is disposed through the inner end ofthe arm 14='so' as" to; prevent it from being forced into the slot 13. totoo greatan extent. I v

Welded or otherwise attached to theface lower, end vof this, bracket is outwardly [extended in a ,Vhorizontal plane and "then formed with an upward extension 18 having; I v the treadle 35 A spring 38 is connected to the plank 10' to the arm liand acts to lift guides 19 for a'vertica1plunger20.' The upslot for arm 14. v

' Welded or otherwise attached to the face of the plate 11 is the angularend21 of an upper jaw 22. This jaw extends horizontally outward and the extremity of' the jaw is provided on its under face with the steel block 23. This block and the extremity of the plate whichforms the jaw 22 is notched as at 24,50 as to permit the passage of the plunger 20. "This notch or slot 24serves as a guldefor the staple and prevents it from buckling when it isforced through-the box by the plnngerQO. The upper j aw '22 is also welded or otherwise rigidly connected to the brace or bracket 17. I

I Hingedly'mountedupon the plate 1 1 below the upperjaw is the lower 25 which extends out beneath the notch or slot 24in 1,676,718 PATENT rice;

the upper jaw. A bolt which constitutes a stop. and is designated 26 'passesldownward through the upper jaw and through'the lower jaw.[ This bolt is held to the" upper jaw bytwo nuts 27 and atits lower end carriesahead or'nut 28; A spring 2st: dis posed between the upper jaw and thelower The outer clinching them;

Resting upon the header nut 28 isalever v e '30 'which'at its outer end is provided with a small block31 andfat its innerendhaslan aperture' forthe passage o'f'the pull rod 32.

This rod-extends downward through guides '33 and has its lower end connectedfjby a coiled compression spring 3a to a treadle"3-5. This treadle is hingedly 'connected'to thef plank or. post 10" in any suitable'ma-nner'and obviously when the treadle is depressed; the

' end of the lever 30 upward against the: jaw

25' so asto" hold the outer end of this'jaw snugly up against the box which is :bei'ng stapled.

Engaging over the arid 14: a -yoke 36 having outwardly turned endsiand passing" through'these outwardly turned ends of the yoke'are the two rods 37 whichextend downward and are operatively connected with the arm.- Attached to the block 23' of the upper jaw 22-is an outwardly and upwardly 1 forces downward upon the hinged jaw 25,

this staple guide being formed with a hinged leaf aO'whic'h when opened, permits the re moval of a staple which may have become turned within the machine or which isbent or deformed. 1 The operation of this mechanismis as follows :\Vhen the foot treadle 35 is released, the tension or spring isentirely relieved and the rod 32 will, of course, be moved upward by the action of lever 30. This is due to the fact that the spring 29 thusreleasing the outer end of the lever 30 downward and drawing upward on the inner end of the lever'iiO and the rod 32. While the stapler will work without thiss pring 29,

I find that the stapler actsquicker and much more surely with the spring 29 than without, In stapling the box, the folded corner of the box is placed over the upper'face of the jaw 25 and the treadle is'forced down- Ward, which places the spring 34 under tension, which causes the lever 30 to fo-rcethe lower jaw up against the'upper jaw. The

rods 37Hpass loosely through the ends of the yoke so. that an initial movement pf the .treadle i3 5 maybe made before "the stops'37f on, the rods engage the yoke When so engaged, the downward movement of the treadle forces the arm let downward, and this forces the plunger 20 downward; Astaplehas been previously placed within the staple sition,

guide. It comes, to rest with its head immediately below the plunger so that upon a complete depression of the treadle, the plunger will force the staple through the box and the ends of the staple,strikingthe concaveffaceof the lower jaw, will be turned inward or clinched in an obvious manner. A

release of pressure upon the treadle immeplunger and diately vcauses the liftingof the This device is extremely eflective in stapling chick boxes which require a 'wide staple. may be easily supported in a convenient po= This machine is particularly desirable for overturning wide staples upon paste-board lchick boxes and one of the advantages of thisdevice is. that it permitsstaples to be used which aremuch wider than those co1n monly used in building chick boxes; These chick boxes are made of paperor cardboard and come to the'user in a flat or knocked down condition. The sides and the ends are .folded upward and the ends of the end pieces are folded around the corners of the boxand stapled together and bythe use of very wide staples, the pasteboard or paperis rheld much w more securely and firmly and without danger *,'of being torn apart.

It will be obvious that While I has illustratedv certain details of construction and arrangement of parts which I have found to be particularly effective in practice, many changes might bemadei'n these details without departin from the spirit of the invention as define in 'theiappended claims.

I claim 1. A stapling' machine of the character ment and connected to the plunger, a treadle mounted upon the support and operatively connected to 'thearm', a lower jaw'hingedly mountedupon the support and havingan' upsetting anvil" disposed below said recess, a lever supported below thelowerjawand having oneendl bearing against'the same,

U

j aw upwardagain'st the upper jaw and upon release, of the treadle to cause the lower aw to' move downward away from the the treadle and the inner end of said lever whereby a depression of the treadle will cause the movement of the lower jaw, and means operatively connecting the treadle to the plunger.

5. A stapling machine including a support, a rigid upper jaw mounted upon the support and having arecessed outer end, a staple guide associated therewith, a plunger mounted for movement through the recess in the upper jaw, a lower jaw hingedly mounted upon said support, a lever pivotal ly supported at its middle and engaged at its outer end with said lower jaw, a treadle,
